rr xml docs, II

[Meitnik at aol.com]

Hi,

Ok rrxml gives "callbacks" while processing xml data, but the examples dont 
really show me why have them or use them. These are the "callbacks":
     revStartXMLData elementData
     revStartXMLNode nodeAttributes
     revStartXMLTree
     revEndXMLNode
     revEndXMLTree

would someone please show me better examples or reasons for these? TIA

Andrew
